Understanding APIs with FastAPI

Real-Life Analogy: Restaurant Waiter

Imagine a restaurant:

• You (the client) → want food

• The kitchen (the server) → prepares the food

• The waiter (the API) → delivers your request and response

1. You tell the waiter what you want (request).

2. The waiter gives the order to the kitchen.

3. The kitchen prepares it.

4. The waiter brings it back to you (response).

APIs work exactly like the waiter. Your program (client) sends a request to the API, and the API gives back a response.
